The pilots soon noticed that the weather was getting worse, and agreed that they would turn left after crossing Krishna River.

Begumpet and Shamshabad Air traffic controllers lost contact with the aircraft at 9:02 am IST while it was passing through the dense Nallamala Forest area.

Thereafter the helicopter crashed due to loss of control resulting in high rate of descent in down draught.

The helicopter impacted the ground in a steep left bank and all occupants on board died due to crash injuries.

[11] The Indian Prime Minister's Office confirmed the helicopter's crash on the morning of 3 September and the death of all aboard, including that of Y. S. Rajasekhara Reddy.

[16] The investigation eventually concluded that the factors that caused that crash included the fact that the crew became fixated for more than six minutes in trying to find the reason behind the problem with their transmission oil pressure system, and they became distracted from the worsening weather.
